Aluminum Composite Panel (ACM) vs Cross-linked PVC Foam Core

Composite · grade comparison

Aluminum Composite Panel (ACM) and Cross-linked PVC Foam Core are both composite grades. Aluminum Composite Panel (ACM) is the stronger of the two: tensile strength 130 MPa (18.9 ksi) against 3 MPa (0.363 ksi) for Cross-linked PVC Foam Core, about 52 times as much. Cross-linked PVC Foam Core is lighter (0.08 g/cm³ vs 1.35 g/cm³ for Aluminum Composite Panel (ACM)) and Aluminum Composite Panel (ACM) is stiffer (70 GPa vs 0.1 GPa). On the shop floor, Cross-linked PVC Foam Core machines more easily (excellent vs very good) and Aluminum Composite Panel (ACM) sits in a lower cost tier (standard, $$) than Cross-linked PVC Foam Core (premium, $$$).

Aluminum Composite Panel (ACM)Choose it when strength drives the design, or when the part sees heat.

Cross-linked PVC Foam CoreChoose it when weight is the constraint, or when the part is machined in volume.
